Overview
The STM6513SEIEDG6F, produced by STMicroelectronics, is a dual push-button Smart Reset device designed to enhance system stability in various electronic applications. This component features two separate delayed Smart Reset inputs (SR0, SR1) that, when activated simultaneously, generate reset outputs after a user-selectable setup delay. The device is particularly useful in applications requiring reliable and delayed reset responses to prevent unwanted system resets.
Key Specifications
| Parameter | Description | Value |

| Reset Outputs | Dual outputs: RST1 (active-high, push-pull), RST2 (active-low, open-drain) | RST1 and RST2 go active simultaneously after tSRC delay |
| Reset Pulse Duration | tREC1 (user-programmable by external capacitor), tREC2 (factory-programmed) | tREC1 adjustable, tREC2: 210 ms (typ.) or 360 ms (typ.) |
| Operating Voltage | 1.0 V to 5.5 V | VCC monitored with factory-programmable thresholds (1.575 V to 4.625 V typ.) |
| Supply Current | Low supply current | 3 µA |
| Operating Temperature | Industrial grade | –40 °C to +85 °C |
| Package | TDFN8 package | 2 mm x 2 mm x 0.75 mm |
| Compliance | RoHS compliant |

Q & A
- What is the purpose of the STM6513SEIEDG6F?
The STM6513SEIEDG6F is designed to provide a reliable and delayed reset response in electronic systems, preventing unwanted resets due to short push-button closures.
- How are the setup delays (tSRC) selected?
The setup delays are selected through the TSR pin, which can be connected to ground (2 s), left open (6 s), or connected to VCC (10 s).
- What are the types of reset outputs provided by the STM6513SEIEDG6F?
The device provides two reset outputs: RST1 (active-high, push-pull) and RST2 (active-low, open-drain).
- How is the reset pulse duration adjusted?
The reset pulse duration (tREC1) is adjustable by connecting an external capacitor to the TRECADJ pin. The tREC2 duration is factory-programmed.
